1. As to ships hitting each other at 42 km/sec I think you could pretty
much consider each vessel to be pretty well totaled. Considering the
distances this would be a difficult collision to bring off.
2. As to ejection seats I see no reason why fighters wouldn't have them.
However, you should consider the difficulty in tracking down all the
pilots who rocketed out of the battle and are now on who knows how many
different vectors going no particular place at a high rate of speed. Hope
their side won the battle and has time to track them all down.
